Contact type coordinate locator with annular luminous display

Abstract

The invention discloses a contact type coordinate locator with annular luminous display. The locator comprises a contact, a shell and a reset mechanism in the shell, and is characterized in that: the shell is divided into an upper shell and a lower shell; a luminous display unit is arranged between the upper shell and the lower shell; a luminous body of the luminous display unit triggers to turn on / off an electric signal switch through the displacement of the contact; and an annular light transmitting body is annularly exposed at 360 degrees between the upper shell and the lower shell. According to the invention, the coordinate positions of the center of the lathe spindle relative to a workpiece hole, side and workpiece center can be quickly and accurately determined, and the data such as aperture, width, height, depth, angle, curved surface and the like of the parts can be measured. The contact type coordinate locator with annular luminous display can ensure that the trigger signal is observed by eyes of people, the repeated location precision of the locator can reach 0.001 mm which is 10 times that of an optical coordinate locator, and the location speed is 3 times higher than that of the optical coordinate locator.

Description

【Technical field】 [0001] The invention relates to the field of on-line precision measurement and processing of numerical control machine tools, in particular to a high-precision contact coordinate locator with a ring-shaped luminous display. 【Background technique】 [0002] When machining a CNC machine tool, when a certain hole center needs to be used as the machining reference, the center of the machine tool spindle and the center of the hole need to be coincident at the same coordinate position. For such positioning measurement, especially the positioning measurement of small holes, the operating technology It is very difficult. [0003] Usually, people use an optical coordinate locator to center and patrol the workpiece, but the speed is slow and the accuracy is only 0.01mm. [0004] In addition, a lever dial gauge is used for positioning. Although the lever dial indicator can be used to determine the position of the hole, it is necessary to manually swing the spindle of...

Problems solved by technology

However, since the original measurement function of this contact three-coordinate measuring head is used when the measuring head (seat) is fixed, if the measuring head is used to realize the coordinate positioning function of the machine tool spindle, the measuring head must be clamped on the machine tool. Make a rotary motion on the main shaft, so that the contact rotates and touches the edge

However, since the existing measuring head does not have the function of displaying upon contact, it cannot perform center coordinate positioning, nor can it take advantage of the high-precision reset of the measuring head
